The P2 Excursion aircraft is the first aircraft design made by the cooperative EAN (Equator Aircraft Norway SA).

General Aerodynamics

The P2 Excursion is a true high performance hybrid amphibian aircraft, with sleek laminar flow aerodynamics. This is emphasized firstly through the shape of the fuselage, which is one continuous "droplet" shape, to allow the air to flow as smooth as possible past the aircraft, without getting upset turbulence and extra drag. Secondly the "float wing" system which removes the need for bulky sponsons and other supporting geometries, and thirdly through the very small electric engine on the tail. Added to the mix is a retractable gear system of course to ensure the best characteristics possible on land and water. With these aerodynamic properties the aircraft may perform like any other land based aircraft. As such the compromise is reduced compared to other amphibious aircraft, that typically get worse properties due to their water capability.

Lifting Surfaces

The wing uses a NACA laminar flow profile, with a 1.4 deg blended twist. The span is about 10m dependant on the type of winglets chosen, they are modular and can be exchanged simply.

With the flaps extended the aircraft should reach a stall speed of 45KT, and on cruise you should be able to fly comfortably at 130KT.

The T-Tail horizontal stabilizer is large (3.8m) on the prototype to be able to adjust it down in size during testing. The size is critical to be able to counter the pitch down moment produced by the engine placement.

Materials

The aircraft is a pure composite design, metals and other corrosive materials have been left out where possible. Carbon Fiber reinforced epoxy is used extensively, with kevlar / carbon hybrid textiles used around the cabin area.

Usability

The P2 was designed from the ground up to be a highly practical aircraft. It is made for 2 people initially (with a future option for 4 seats) with focus on comfort Therefore the cabin is much larger than what is common in light aviation sporting a 1.50m wide cockpit.

Much of the research done initially was focused on the situation when the aircraft is a boat with wings. How to get in and out practically, and how to manouvre the vehicle simply. The result is an open cabin with waterproof surfaces. The pilot can exit and enter the plane over the nose, and over the railings. This flexibility is unique, and coupled with simple and reduced avionics, we end up with a very open solution.

The baggage area is huge as the whole aircraft can be used, you´ll be able to store bulky luggage such as bikes, skis etc.

The P2 has no rudder pedals. Jaw control is done through twisting the stick around the vertical axes, and is being developed as a FBW (Fly by Wire) feature on the plane.

Engine System

The hybrid propulsion system being developed by Equator is called EHPS (Equator Hybrid Propulsion System). The engine specific project is being co-funded by Transnova and the company doing the development work with us on this is ENGIRO. We will design a custom engine and generator specified specifically for the P2. Power out in the prop is 100kW (approx. 130HP) and the generator will produce 57-60kW of power charging the batteries. The combustion engine will be a wankel engine that runs on bio-diesel fuels and jet-fuel. The fuel tank can hold 100l and this should give you a flying time of 5-6 hrs max.

The aircraft being developed is a proof-of-concept vehicle, to prove that all the new systems being integrated work and can be put into production. The prototype is being built in a low cost manner, without expensive molds (moldless). The work started in 2011, and the prototype should be completed within Q2 2015.

This page will be updated with the properties as the aircraft closes on completion and test flights are started. We wish to tell you that the numbers mentioned here are estimates only and will be revised as we go along.

Story

The Legacy of G. Poeschel

Guenter Poeschel and his team successfully built and test flew three Equator prototypes in the years between 1969 and 1981. The Equator idea at the time presented a very unusual modular aircraft system. As both amphibian or landplane.

They were designed to be perfect for unusual mission abilities to make profit day and night, during all seasons. The modular-system ranging from 2-4-6-8-10 seater up to 12 passengers, in the cabin- or wide-body class. From the low-price landplane with fixed gear and piston engine single up to the pressurized turboprop twin amphibian with center line thrust up to the 20 seater commuter and jet amphibian.

The unique design ideas, is the combination of known and proven conceptions put together in new ways to achieve better characteristics. Sadly the P-300 A2 never reached production due to the downfall in the aviation markets in 1980 to 1990. But never the less the will-power and belief that goes into producing some of (at the time) largest composite aircraft in the world with a wide array of new technologies on board is an amazing feat to say the least. The aircraft produced is a testament to the beautiful mind behind them, and is a strong legacy that EAN will aim to follow continuing the work done and ideas resolved.

A more extencive history on the Equator legacy is being worked on at the moment, but the following three aircraft testbeds were made in the period EAC was active.

The test area used in the vintage footage of the Equator testbeds P-300 A1, P-300 and the 420 is designated Ulm, Laupheim (military base) and Erbach Airfield. The P-300 testbed prototype can today be viewed at Erbach Airfield, and Equator Aircraft is working on restoring this aircraft.

Make prior contact with Guenter Poeschel, and he will gladly give you a tour of the aircraft with the addition of the whole story behind the aircraft.

Tomas Brodreskift met Guenter in Southern Germany where he worked at the time in 2008. Visiting often and learning about the amazing aircraft that were developed was inspiring, and he decided to take the P2 (the smallest concept) back to Norway and develop it further with partner Oeyvind Berven. About two years and almost 8000 work hours was used to finish the new P2 concept that is being prototyped at the moment.

Equator Aircraft Norway SA is a cooperative organisation registered in the Norwegian Company Registry with company number: 996347990MVA. The company was established in 2011 to develop the P2 P.O.C prototype.

The members involved are investing both time and money to realize the goal of first flight of the P2 in 2015. Most of the members have other day jobs, and work on Equator projects in their free-time. At this stage we are currently 11 cooperative members + 3 external expert members.

Equator Aircraft is an agent for unique aircraft design, we are very interested in getting contact with young, highly spirited engineering- and design students.

In 2008 the two Industrial Design students and pilots Tomas Broedreskift and Oeyvind Berven started work on the new EQP2 Excursion, Equators first attempt on the light aircraft market. In this start – up phase the Equator team are working on making project assignments, design briefs, and specified diplomas that can be worked on by students. Therefore we encourage every student with relevant studies and an aerospace dream to join our efforts and in time become part of the new Equator Team that will ultimately bring amphibian flying to a new level. Objectively spoken, your fantasy truly is the only limit! We have several areas that need to be researched and tested before we build our EQP2 Prototype Testbed. We will of course provide the guidance and motivation you need to do an excellent project!

If you are interested in the aerospace industry, this is a unique possibility, where you might end up seeing many of your ideas come alive on our EQP2 Excursion Design Package, and perhaps on the whole future P-Series. You have the opportunity of coming in contact with a pioneer within the development of composite aircraft Guenter Poeschel, and get ideas realized through Equator Aircraft and our cooperatives.

Contact our Student coordinator Tomas Broedreskift for further information on how we might proceed to cooperate on specified product assignments. And if you´ve never flown in a small plane in your life, we might even be able to fix that to!

Some of the student projects that have been completed with great results so far can be seen here.

Enjoying a period in the workshop, and we were so lucky to have Kristian who is just as big an aviation geek as we are helping us out. Yesterday we installed brackets for large electric controllers, 2 down, 2 to go;) #equatoraircraft #eqp2 #xcursion #eaa573 #aircraftdesign http://ift.tt/1TSSF00

Finishing off the wing skins after control alterations. Took a few weeks, but now it works "oh so good"! Better "feel", and more precise input vs. output;) #aircraftdesign #equatoraircraft #eqp2 #carbon #carbonfiber http://ift.tt/1HPWIGu

Little progress update from the workshop! Still digging into details, thus fewer posts, but yesterday we started to assemble the centre sections, we put on the motor fix (big silver block in the middle) and all the walls surrounding the motor. This is the first step in completing the biggest and most complex part of the aircraft. The goal for July - August is to have this mounted in the fuselage. #aircraftdesign #equatoraircraft #eqp2 #eaa573 #carbon #carbonfiber http://ift.tt/1C5zGL9

Doing some final mods to the flaps and ailerons, and prepping the elevator for some load tests today. Lining up our parts for what looks to be an interesting summer where all items should come together. #eqp2 #equatoraircraft #aircraftdesign #elevator #ehps #enova #carbon #carbonfiber #eaa573 #aircraft #airplane http://ift.tt/1FnkCK8

Got a nice linkage to the e-genious project being worked on in Stuttgart on the CAFE blog today http://blog.cafefoundation.org/, Our propulsion developers at ENGIRO have also made the 20kW range extender for the e-genious. Nice to be mentioned together with such a great project, with which we share so many similarities.

Back on the "job" after meeting many amazing people at the #aero15. Inspiring to note that everyone shares the experience of being a start up in one point of time with all that it entails! The huge progression in electric and sustainable systems being made are proving that we are on the right track with our product, and we cannot wait to show it off at some point at the greatest expo in Europe and maby even the world. But alot of work has to be done to get there, so let's go! #equatoraircraft #eqp2 #workshop #aircraftdesign http://ift.tt/1aNTLZf

A BIG congrats to our Swedish friends at #blackwing for exhibiting an awesome #aircraft with performance that puts most UL aircraft to shame! The #aerodynamic work that was put into this machine is above and beyond! It is such a joy when such things are displayed;) #swedishaircraft #eco1 #textreme #carbonfiber #aircraft #airplane #aircraftdesign #aero15 #eaa573 http://ift.tt/1yyZyNY

A #testjig for the M97 electric engine fixation to the #eqp2 #xcursion aircraft. With this we can test forces in all directions to make sure the motor will stay on the aircraft under all conditions. #aircraftdesign #equatoraircraft #ehps #transnova #enova #eaa573 http://ift.tt/1HDAyI1

Another #ehps workshop to develop the drivetrain system hardware and software completed @sintef. It's really challenging, but with talented engineers anything's possible. Closing in on some final results to be tested soon. #equatoraircraft #eqp2 #xcursion #transnova #enova #aircraftdesign http://ift.tt/1BOZOaK

The EQP2 Xcursion is designed with a lifting body, which in essence means the aircraft produces lift not only over the wings, but also on the body itself. Several CFD processes were conducted to verify these properties, among others Aerospace Engineer Aleksey Matyushev from the US helped us in creating all the aerodynamic research in this project.
Many benefits can be produced from having a lifting body design, the main one being less wing span, but our primary goal is to have less lift, thus less drag on the wings during cruise to achieve a higher cruise speed. If this happens will only be shown in test flights though, because we have not had the ressources to do wind tunnel testing.
Another item we're concerned with is the "pull" this lift creates on the canopy. The CFD image below shows research done to create canopy locks that are strong enough to hold the canopy in place under a high G pull @ high speed. As you can see the blue area shows low pressure gathering right on top of the glass, an approximation shows we had to dimension the locks to hold (worst case) atleast 600kg of pull.. Which is alot!

The #eqp2 #xcursion fuselage still fairly emty in the middle, but closing in on filling it with the main assembled interior and structural parts. Working on the nose gear hatch and cable guides in the tail today. #equatoraircraft #aircraftdesign #electricflight #amphibious #eaa573 #eaa #experimentalaircraft http://ift.tt/1DQcLkO

We are prepping the wings for the big load-test coming up. We will stress the wings to approx 7.5G's using the #wiffletree method with car jack's to apply force to the points that are re-inforced here with #polyester, heavy glass fiber and wood to distribute the loads. This is a crucial test that is the last hurdle before final assembly of all the parts. Stay tuned for a film, showing (hopefully) a successful test! #wingload #aircraft #aircraftdesign #equatoraircraft #eqp2 #xcursion http://ift.tt/16clx08

It will be a race to finish the #eqp2 in 2015, many details to sort out every week, here working on electric motor cooling, console finishing and wiring and a new power lever. #equatoraircraft #xcursion #eaa #experimentalaircraft #carbon #carbonfiber #aircraftdesign #avgeek #aviation http://ift.tt/1EmTM07

Custom #batterybox being put together @ #mgmcompro. 108 cells each with it's own little #PCB. Never thought we'd get into battery design when we started the #eqp2 project, but there really was not many options in this department. Anxiously awaiting trials of this #LiIon 2kWh boost pack. #equatoraircraft #aircraftdesign #transnova #xcursion #experimentalaircraft #electricflight http://ift.tt/1DpAZRm

Finally got some fixing points for the electric motor ready. They are angled to the centre of the prop for evenly distributed force when thrust is applied. The rubber vibration dampers are #continental spec, with AN6 bolts holding it all together. Moving forward we will load test these guys and verify the molding and laminates applied. #equatoraircraft #eqp2 #xcursion #aircraftdesign #enginefixture #eaa573 #experimentalaircraft http://ift.tt/1AwVg5z

Typical late night trying to solve an issue. This is the second prototype of a power lever (throttle) and brake handle for the #eqp2. The throttle is controlled by electric signals from two potentiometers, also there are similar components in the upper handle to reverse the propeller and back up in water, an awesome feature that is made available by having electric propulsion. The lever will also be the brake for the main undercarriage. The prototype will be 3D printed shortly and tested, but first; all details must be thought through. #equatoraircraft #solidworks #cad #construction #xcursion #experimentalaircraft #eaa573 #aircraftdesign #throttle #electricflight #transnova http://ift.tt/1z6xdMe

Just fixed the motor nozzle to the tail, to ready it for the engine fixture we've been working on the last week. Should be cured and ready tomorrow. Within the end of next week the electric motor can be put on the aircraft. #carbon #equatoraircraft #eqp2 #xcursion #aircraftdesign #aircraft #avgeek http://ift.tt/1Bo8LYT

Working on the #carbon machine fixture this week. Making a super strong cylinder for the electric motor. #aircraftdesign #eqp2 #equatoraircraft #xcursion #experimentalaircraft #eaa573 http://ift.tt/1vIRvJ9

Elevator coming together. Just did the trim hinge, and now what remains are the end pieces, counter weights and fitting the control items and electronic trim system. #elevator #equatoraircraft #eqp2 #xcursion #experimentalaircraft #eaa #aircraftdesign http://ift.tt/1Hqdfjf

A plethora of simultanious details being worked on, the parts to fabricate become smaller but increase in quantity. Fuel tank ready for sealant, motor nozzle fixture and air ducting, elevator completion, and many more! Closing in on final assembly. #equatoraircraft #eqp2 #xcursion #aircraftdesign #carbon #construction http://ift.tt/1zsWejd

The basic design for a 2kWh "boost" #batterybox for the #eqp2 was "completed" this week with help from #tronrocks / Andersen industrimodeller and sent off to #mgmcompro in the Czech Republic to be completed with cells and electronics (image holds one cell). The shape as such is made to fit in a bay in the nose of the aircraft. This battery will boost the motor with an additional start power of approx 40HP for 3-4 minutes. We assume this is required to get out of water. The battery completion will surely require some modification. But for now the #ehps hybrid system is coming together. #transnova #aircraftdesign #equatoraircraft #xcursion #batterydesign #kokam http://ift.tt/1sgAl1w

Alot going on in the #workshop today. The horizontal stabilizer came in and we started finishing work, motor nozzle detailing and Sections 10 and 11 fitting with flaps actuator rods. Prepping all for final assembly! #eqp2 #xcursion #equatoraircraft #aircraftdesign #experimentalaircraft #avgeek #rcaircraft http://ift.tt/1yJF54v

This evening we are Interfacing the generator to the carbon brackets we will fix in the engine bay. The vibration mounts come from #rosta of switzerland and are fixed to our own welded steel angles that are mounted on the motor. The attachment surface is a glass fiber re-inforced plate, high temp material called HP-1, this is then laminated to the carbon brackets to ensure a perfect fit and alignment. #ehps #aircraftdesign #eqp2 #xcursion #equatoraircraft #wankelsupertec http://instagram.com/p/uigYgrt7ms/

Working out at Per's workshop, doing the final laminations before the horizontal stabilizer is closed. Note to self: always have hundreds of cool model aeroplanes around the shop, it makes for an inspiring backdrop to any #aircraftdesign process. #eqp2 #xcursion #equatoraircraft #aircraft #experimentalaircraft #stabilizer #carbon http://ift.tt/1vAssu6

Another delicate part arrived in the workshop yesterday. The #custom #propeller from #DUCHelices in france. The hub is milled from high grade aluminium to fit our #ehps #aerodrives M97 electric engine, with an air ducting right through the prop. As such the Ø300mm spinner is also custom molded in #carbon. The blades are (OTS) DUC #flash Ø1850mm carbon with metal leading edge protection, good for water splashes, and excellent aerodynamic properties. They did beautiful and efficient work! Can't wait to see this thing on the #xcursion #equatoraircraft #eqp2 #aircraftdesign #aircraft #avgeek #aviation #experimentalaircraft http://ift.tt/1wEw0bk

Oh boy! Christmas came early this year. A dummy of the #eqp2 #xcursion #ice #turbowankel #kkm352 (internal cubustion) part of the generator came into the workshop today from #wankelsupertec. It will be used to interface our composite brackets and engine bay, before the whole generator is due for delivery by the end of the year. Sure is great to finally get our hands on some #ehps hardware! #equatoraircraft #aircraftdesign #aerodrives #avgeek #motor #generator #wankelsupertec #transnova http://ift.tt/1sxooIp

Just completed the "stablet"/top of the tail and one of 2 end pieces for the elevator. They were made in female styrofoam molds, covered with wax to even out the surface, then a layer of twill peelply was applied wet before putting in the carbon (hand layup w/o vacuum). An experiment on a semi-"cheap" quick method for fabricating ultra light hollow carbon components. There will be some work required on the outside, but in the end they will look excellent. #eqp2 #xcursion #equatoraircraft #aircraftdesign #aircraft #experimentalaircraft #aviation #avgeek #carbon #molding http://ift.tt/1C8PA1a

Right side of the vertical stabilizer tip being machined into a female mold at Shape AS on the west coast of Norway. The idea is to mold a carbon skin from this PUR shape, thus creating a very light weight part.

The #eqp2 #xcursion #aircraft will have a FBW (fly-by-wire) rudder, actuated by rotating the stick around it's vertical axes, like you do in some computer games. There are no pedals anymore. Relax and put your feet up! The question for pilots out there is: What do YOU think? Easier or harder to make precision xwind landings? #aircraftdesign #equatoraircraft http://ift.tt/1udjhO9

The tail section came on over the weekend, and the rudder is now beeing tested with the FBW servo. It is looking really good, and it is yet another small milestone in this project. The two hatches on the tail are openings for fixing the servo (upper), and putting in one elevator bell cranck (lower). The skin on the left side of the tail (not visible) will be left off until all items are installed (cables, fixes, etc.).

One completed rudder with water-rudder sticking out of the lower part. Weighing in @ 2.3kg, it could probably be lighter in a different process, but damn good to have it done! #equatoraircraft #eqp2 #xcursion #carbon #experimentalaircraft #aircraft #aircraftdesign #avgeek http://ift.tt/X7KpAR

Just put the wings in an oven for curing! 10hrs@60C.. Afterwards these wings are ready for a grand load test to verify the structural integrity. #eqp2 #equatoraircraft #aircraftdesign #carbon http://ift.tt/1tjbC1C

Why post a fricking pic of a metal box?? Well it's the mock up for a 10K Euro #batterybox for the #EHPS and #EQP2 aircraft. The cells will go in the main housing and the BMS electronics will go in each end piece. The actual box is being made by friend and prototyping specialist Tron Andersen. ➖➖➖➖➖➖➖➖➖➖➖ #tronrocks #equatoraircraft #transnova #aircraftdesign #electricflight #xcursion http://ift.tt/YFjfCy

A big warm welcome to our latest intern Sebastian Reymert, who is currently studying aeronautical engineering in London. He's helping us out a month during the holiday, with the rear structures and control items, readying the final pieces for assembly.

Some quick gear extend/retract actuation footage showing the status on the center section. This is finally completed now. Only some minor lamination to be done. Then the whole thing will mate with the fuselage, and create something that looks more like an aeroplane.
These things take alot of effort; 4 mechanical principles, and alot of different ideas were tested prior to this final solution. But what we get is a completely closed cavity that is good for both the aerodynamics and hydrodynamics of the P2. But, retractable gear systems is "no joke"!

Machined propeller hub made in france by #duc! #ehps orange finish! Can't wait to get the set up on the aircraft. #equatoraircraft #eqp2 #propeller #avgeek #aircraftdesign #aircraft http://ift.tt/1os7EjJ

High lift devices, namely flaps and ailerons hinged to the wing. Slowly closing in on completed wings, what remains is wingtip attachment, fine tuning aileron control, and quite abit of surface work and finishing!

Airbus is ramping up in light aviation. Hopefully this will provide even more good technology to emerge within the industry! At first glance the concept drawings almost resemble the Equator P2 canopy! We love alot of glass, for the viewing pleasure and flying experience.

With a great effort we "updated" our tent-workshop at NorPel AS last week. We cleaned out the whole space and re-organized the area, clearing it for the next stage where we will bring in all the parts for assembly over the summer and coming autumn. Proper facilities is important, but working out of small workshops makes organizing equipment good much more relevant. We hope this will help speed up the process, and enable us to start final assembly asap.

The winglets came in from Shape yesterday, and are looking good. We just put on the first layer of laminate this evening. As seen on the images the whole wing system with centre section and wings has been put together to work on the surfaces, and gear.

Milling of the winglets started today at Shape AS in Ålesund (west coast), we're doing a styrofoam positive plug, and will laminate directly onto the foam (after aditional surface finishing) Then the idea is to use acetone to "emty" the shell, by melting the styrofoam. Probably the cheapest and least time consuming way to finish a one- off set of winglets. Anyone out there ever try this method? We'd be happy to get tips or advice!

Last couple of days saw the finalization of the major wing lamination and now it's on to details like hatches and the aileron and flaps. Here Gabriel is working on one of our "signature" composite hinges. Also we started reinforcing the centre section today which is the last really heavy duty action!

Welcome our latest intern Gabriel Pirmez, who travelled all the way from Austin TX to join us for 2 weeks in our endevours. Here about 12 hours after arrival; sanding away at the wing surface! Great to have you here Gabriel, welcome to Norway!

This weekend we put in the final of 4 reinforcement linings in the wings, completing the main spars. Quite a big job that took about 3 days total, 17 layers per surface, of 200mm 315g unidirectional plys will give us strong and rugged wings designed both for forces in air and on the water. Now what remains is finishing the surfaces and putting on the ailerons and flaps, and finally of course making some nice winglets to grace the tips.

Used this beautiful Sunday to get reinforcement carbon flanges down in one side on the left wing. Moldless construction leaves us with few options in regards to how this is done, so decided to "go in" from the outside, which insures the wing shape is intact, but of course means we have to re model the outside skin after the 17 layers of uni directional carbon is put inside the milled crease. 3 sides to go and then these wings will hopefully be able to take huge loads!

Some of the things going on in our CAD model are: Finishing of rear fixtures for flaps and elevator, cooling system for electric machine rear, cooling system for the battery pack. And in general a lot of routing wiring and tubing.

Yesterday evening we could finally release the top skin and structure from the bottom skin. It is always a risk that the laminate has passed the protective release teip, and that was the biggest fear. But it was pleasing to see that none of our fears were confirmed and the partition went smoothly. Now we have to do alittle "big" work before closing the wings, hopefully giving us lifting devices before easter has passed✈️ #aircraftdesign

Only a few days now before the AERO opens once more. We will be on the grounds from Tuesday walking around to look at everything new. If anyone wants to get in touch to talk, please feel free to send an e-mail to: tb@equatoraircraft.com, call or text +47 970 39 469 or simply drop a message here on facebook.

After many details on the main gear were completed we finally attached the top wing skin today. Another small milestone on the way toward completed wings. It will be exciting to release the mould in a couple of days to analyze the results. Fingers crossed the wings will be closed before easter has passed, and we can move on to the fuselage, and the home straight on the construction, still aiming for a completed prototype aircraft this year.

As we started working on the wings about 4 months ago we got to use a spot in a local factory NorPel AS. Here we made a small tent where we keep the temperature up for laminating and the dust from the factory out. Though not ideal it gives us enough space to finish the aircraft, without spending money on housing. A big thank you goes out to NorPel for letting us "play" in the corner!

It was great to see the gear finally attached to the main bulkhead yesterday. Here are some more images. The movement and mechanisms fit well. Now we have to attach the actuators, which are electric motors running a threaded rod.

To accommodate hot cables, special plastic #Polysulphone (PSU) brackets are made to fix them inside theP2 aircraft. PSU can take up to 200 C over long periods without deteriorating. #aircraftdesign ✈️ http://ift.tt/1f9cSbb
